Hello all

just about to fit new polybushes to a low mileage omega estate 53 plate after a chance meeting with this forum's Entwood (cheers Nigel!) and a question arises:

please can someone confirm what are the torque settings for the polybush centre nut/bolt and also for the rear wishbone nut which is to be loosened to give some cleaance on fitting.

There is reference on here to "standard settings" but I can't find those!!

Also, is the percieved wisdom still to torque up with the wheels bearing the car's weight and therefore on ramps?

many thanks

No need to undo the rearward bush. Won't help anyway.

And to be clearer, polly do not need to be tightened wheels loaded.

Hi Chris

thanks for the replies and info/link. Sorry i havent thanked before but i didnt receive an email alerting me to the answer!

Re your comment above, sorry to be a pain but are you saying that unlike normal bushes, the poly bushes can be torqued with the car on axle stands rather than ramp?

With poly bishes are you still recommending running back and forth to settle?

also do the polybushes have a shorted life expexctancy?

cheers

ide of thort they would out last a standard bush because they dont perrish or soften over time....

[Kevin Wood]

Poly bushes can be bolted straight up (same torque settings) without any requirement to load the car or settle the suspension. This is because the central tube actually rotates in the bush as the wishbone pivots. With a conventional bush this movement is achieved by the rubber twisting so it was important to ensure that no strain was on the rubber in the "normal" settled position.

Many thanks both - sounds like the job may be a little more straightforward then....

Surely the bush rotates around the sleeve that is firmly clamped by the bolt through its centre?

Depends which way you look at it, I suppose.

By far the worst bit of this job is removing the old bush without cutting into the wishbone.

That done, provided there is room to swing the torque wrench, it's litterally 5mins work to fit the polly bush halves and sleeve, bolt it all up, drop the car off the stands  job done. No wheels loaded, no settling suspension, no messing.

Hi Chris

yes, i am psyching myself up to do it!! but please forgive me being pedantic:

re the torque settings, i see that the instruction is 120Nm then angle 30 deg then 15 deg.

Ok I get taking it to 120Nm then 30 deg but are you saying a) then  wait  (and tighten a further 15 deg or b) slacken off and retighten to 120Nm plus 15 deg

thanks

You've top trumped The Boy re one word answers ................. you've managed with just a letter!   

[feeutfo]

Why write it twice? He's done the work for me, bless him.

[rds]

not so fast: you didn't say how logn to wait for before continuing the remaining 15deg (that question was implicit in a)!
cheers
